Late development of dissecting aneurysm following balloon angioplasty of native aortic coarctation.

Acute aortic dissection during balloon angioplasty for coarctation of the aorta or aneurysm formation during follow-up are well-known complications of this procedure. Dissecting aneurysm development during long-term follow-up after balloon angioplasty of a native coarctation has not been previously reported. We report a case in which a huge dissecting aneurysm developed 3 years after the native coarctation angioplasty procedure.
